SigOFIT ™ Optical-Fiber Isolated Probes
The Micsig SigOFIT ™ optical-fiber isolated probe offers a galvanically isolated measurement solution for accurately resolving high bandwidth, high voltage differential signals in the presence of large common mode voltages with the excellent common mode rejection capability within its bandwidth range.
Suitable for any oscilloscope with standard BNC interface and 50 Ω impedance
Features
- Exclusive SigOFIT™ optical isolation technology, common-mode voltage up to 85 kVpk.
- Differential voltage range from ±0.01 V to ±20 kV (depending on the attenuation peak; standard attenuation peaks)
- Supports high-voltage inputs of up to 20 kVpk and a bandwidth limit of 200 MHz, enabling the measurement of high-voltage signals, equipment protection and high-energy testing (ultra-high-voltage attenuator)
- Maximum supported voltage: 5 kV, frequency range: 300 kHz – 50 MHz, accuracy: 1 per cent, no heating or failure (high-frequency ultra-high-voltage attenuator)
- 1 m extension attenuator, suitable for applications with limited space for internal equipment or for longer signal transmission distances (long attenuator (typically 1 m))
- SMA direct connection to the optically isolated probe with 2-stage attenuation for measuring low-level signals (SMA adapter)
- CMRR up to 128 dB at 100 MHz and up to 108 dB at 1 GHz
- 1% accuracy for DC gain
- Fast response, measurement upon power-up, calibration in 1 second, providing accurate real-time signal output
Applcations
- Power device evaluation, current parallel measurement, EMI and ESD troubleshooting
- Motor drive design, power converter design, electronic ballast design
- Design and analysis of GaN, SiC, IGBT half/full bridge devices
- Tests of inverters, UPS and switching power supplies
- Safety isolation test for high voltage, high bandwidth applications
- Wide voltage, wide band test applications
- Floating measurements

The combination of probe and attenuation tip determines the probe’s technical specifications. To find the right tip for your intended application, it is important to correctly identify the key parameters: differential voltage range, maximum input voltage and input resistance. If you are unsure, we recommend contacting our technical support team.
You can find the appropriate attenuator tips on the model’s product detail page.
